But there are some people who run 1/4λ antennas, which would be around 19" tall. But also, as on CB, a 5/8λ antenna generally works better, thus the 4' 2m antenna. Can you wrap the conducting surface as they do with CB antennas? A 5/8λ CB antenna should be around 258 inches (21.5 feet) long, yet they shrink it into a 4' whip. I suppose you give up a lot of RF transfer by doing that...
